Abstract: DEMAND COMPENSATED HYDRAULIC SYSTEM WITH FLOW SENSITIVE DEVICE                  Abstract of the Disclosure A demand compensated hydraulic system includes a pump re-sponsive to pressurized fluid in a demand feedback pilot line.          The pilot line is connected to sense fluid demand between a hy-draulic motor and its associated control valve which is closed by servo feedback from the motor.  A flow sensitive device is interposed in an output line connecting the pump and the control valve to sense when the flow decreases until it is insufficient to operate the function.  At a predetermined decreased flow rate, the flow sensitive device operates to momentarily connect the demand feedback pilot line to a reservoir to cause the pump to go into a stand-by condition.

Abstract: Abstract of the Disclosure The invention concerns extrusion die sets for use in the manufacture of covered electric cables by direct extrusion of the covering material onto the cable core as it traverses orifices formed in the dies of the die sets.   Pairs of dies have conventionally been employed which exhibit features conforming to traditional die design criteria such as for ensuring laminar flow of extrudate to the core to be covered, for ensuring correct sizing of die orifices and relative die orientations, etc.   The invention abandons the traditionally accepted design criteria and provides die arrangements which have been found to be much simpler and less costly to manufacture, much simpler in use requiring less demanding setting-up routines, and to provide improved operational characteristics.

Abstract: NETWORK WITH SINGLE AMPLIFIER FOR SIMULATING FOR CIRCUIT   by Charles E. Schmidt ABSTRACT OF DISCLOSURE     The one-port network here includes a pair of terminals and a single differential-input operational amplifier having an output electrically connected through the parallel combination of a resistor R3 and a capacitor C3 to a first input of the amplifier, through a resistor R4 to a second input of the amplifier, and through the series combination of the resistor R3 and a resistor R5 to one terminal of the network which is electrically connected to a ground reference potential.  The second input of the amplifier is also connected to ground through a resistor R6.          The first and second inputs of the amplifier are also electrically connected through an associated capacitor C1 and resistor R2 to the other terminal of the network.  With the capacitances of the two capacitors normalized to values of unity and with the initial constraint that the normalized conductance of the resistors R4 be equal to the sum of the normalized conductances of the resistors R2 and R6, the admittance presented across the network terminals corresponds to that of the parallel combination of an FDNR, a capacitor, and a resistor.  With the additional constraint that the product of the normalized conductances of the resistors R3 and R6 be equal to the product of the normalized conductances of the resistors R4 and R5, the impedance presented across the network terminals corresponds to that of the parallel combination of an FDNR and a capacitor.  With both the initial constraint and the alternate constraint that the product of the normalized conductances of the resistors R4 and R 5 be equal to the sum of the product of the normalized conductances of the resistors R2 and R6 and  the product of the normalized conductances of the resistors R3 and R6, the impedance simulated across the network terminals corresponds to that of the parallel combination of an FDNR and a frequency-independent negative resistance.  The network impedance is converted to that of an ideal FDNR by connecting a resistor having an appropriate resistance across the network terminals.

Abstract: TROUBLE LIGHT UNIT            ABSTRACT OF THE DISCLOSURE:   A trouble light unit molded, in preferred embodiment, of plastic, except for those elements required to be con-ductive.  One end of its tubular handle defines a receptacle receiving a spacer block to which is slip fit a lamp socket and switch device mounting female terminals received and frictionally clamped in their required position by clips integrated with the spacer block.  The frictional clamp of the terminal elements ties the lamp socket to the spacer block for insertion thereof as a unit as a diametral split in the outer end portion of the receptacle wall structure accommodates laterally projected portions of the included switch.  The spacer block is designed to seat within the receptacle to position and maintain the female terminals in alignment with slots in the wall of the handle.  A reinforcing plate providing a polarity bridge is incorpor-ated in the handle wall structure to maintain the required configuration of the slots.  The spacer block includes an integrated ground terminal an opening to which is placed in alignment with an aperture in the wall of the handle having a predetermined relation to the polarity bridge and the included slots, to serve therewith to provide an electrical receptacle.    A sleeve-like insert applied in receptacle end por-tion of the handle forms substantially dead air space -1-               (cont. on la) within its interior wall surface which insulates the body of the inserted lamp socket.    A preferred lamp or bulb cage for use with the handle incorporates a generally imperforate backing portion which permits soft light to pass and an angularly related portion which underlies the bulb and provides vents inducing air flow facilitating the escape of heat from the caged bulb or lamp.    The handle also incorporates plate-like projections which shield the switch operator and preclude direct impact thereof on a surface against which the total assembly may be dropped or bumped.
